  • Thymalin
  • Thymic regeneration; restores T-regulatory cell production and reduces inflammatory cytokines
  • 5-10mg SC every 48 hours for 10 doses
  • Lyophilized: -20°C; reconstituted: 2-8°C, use within 28 days
  • Immune-endocrine axis
  • Best first-line peptide for HPA dysfunction—addresses the immune dysregulation that perpetuates stress response abnormalities
  • MK-677
  • Growth hormone secretagogue; stimulates pulsatile GH release and IGF-1 production
  • 25mg oral daily for 12-16 weeks
  • Room temperature (lyophilized); refrigerate liquid forms
  • Anabolic signaling, mitochondrial biogenesis
  • Most practical for long-term use—oral administration and stable GH elevation make it ideal for sustained recovery
  • Cerebrolysin
  • Neurotrophic peptide mixture; promotes hippocampal neurogenesis and synaptic repair
  • 5-10ml IM or IV 2-3x weekly for 8-12 weeks
  • Refrigerate at 2-8°C; do not freeze
  • Central nervous system, HPA feedback regulation
  • Strongest evidence for reversing stress-induced hippocampal atrophy—critical for restoring cognitive function and emotional resilience
  • Dihexa
  • Hepatocyte growth factor modulator; enhances synaptogenesis and cognitive processing
  • 1-5mg oral or SC daily (research dose range)
  • Room temperature (lyophilized); refrigerate once reconstituted
  • Cognitive function, neural plasticity
  • Emerging compound with potent synaptic effects—less studied than Cerebrolysin but promising for cognitive recovery
